I need to read in and then combine a variable number of files. I am
trying to figure out how to get the contents of all the files into an
array.
let fileContentsArray = getData ["dataFile1.txt",
"dataFile2.txt"]
getData :: [String] -> [String]
getData [] = []
getData (f:files) = do
fileData
<- readFile f
fileData : (getData files)
I figured I could use readFile to open the files. But, I need to use
<- to get the data out of the IO Action and into a value. I thought I could write a function like the following, but I'm getting no-where. I
suspect I'm missing something basic about IO in Haskell. Can anybody
point me to a good resource....
Thanks,
Tim
